The genuine Goodman 20171701 condensate drain trap is the OEM component that captures and routes condensate away from the secondary heat exchanger on your Goodman 96% AFUE furnace. It is engineered as a direct fit for the GMV951155DXBA two-stage variable-speed gas furnace and related GMV9-series models, maintaining the factory drainage geometry and neutralizing trap seal so combustion gases stay sealed while water flows freely.
The OEM 20171701 matches the original trap volume and port spacing exactly, ensuring a proper trap seal and correct pressure-switch behavior — critical because an incorrect trap can cause nuisance lockouts. A generic universal trap may fit physically but often requires adapters and can alter draft, risking condensate backup into the heat exchanger. For reliable operation we recommend the OEM part.
Easy (1 of 5). The trap typically disconnects with quick-connect hoses or clamps and reseats in minutes. Always prime the new trap with water before firing the furnace and confirm free drainage. If you are unsure about condensate routing, consult a licensed HVAC technician.
Replacing a cracked, clogged, or leaking drain trap restores proper condensate flow and helps prevent pressure-switch faults and water damage around your furnace.
